What Is Preserver Insurance Company?

Preserver Insurance Co. used to be one of 18 subsidiary companies included in the Tower Group of insurance companies. Headquarters were located in New York City, but Preserver also had a location in Jersey City, New Jersey. Preserver was purchased by Tower Group Insurance in 2007 and remained a part of that company until it closed.

Preserver Insurance Co. was licensed to underwrite auto insurance policies in 44 states, plus Washington D.C. The company specialized in package commercial lines of insurance in New Jersey and California and also underwrote fire, marine, homeowners, workers' compensation, and casualty insurance policies.

What Happened To Preserver Insurance Company?

After merging and changing names, Preserver Insurance Company ultimately went out of business for an inability to pay claimants and debts it owed to creditors. Today, its parent company is permanently closed down.

After a major merger of several car insurance providers (including Tower Group Insurance), Preserver Insurance Co. changed its name to CastlePoint National Insurance Company. Years after the merger, all of the companies in this insurance group, including CastlePoint, were ordered to liquidate by a Superior Court in San Francisco.

The CastlePoint company was found to be insolvent, which means it didn't have enough cash flow to pay its creditors and the situation was bad enough to warrant an order of liquidation. 

In 2017, the Insurance Commissioner of California brought CastlePoint to the Superior Court to apply for its liquidation. According to court documents, the court found sufficient grounds that CastlePoint was legally insolvent.

Furthermore, the court found it was futile for CastlePoint to continue in business and that it would ultimately hurt its customers in the long run. Here's a quote from the Conservation Order in 2017:

"CastlePoint [...] is in such condition that its further transaction of business will be hazardous to its policyholders, creditors, and the public."

- Superior Court of California, San Francisco

Remember, a car insurance company is responsible for paying claims to cover damage and injury when its customers get into accidents. Ultimately, CastlePoint (previously Preserver Insurance Co.) was unable to do that as it went into insolvency.

As of April 1, 2017, none of the Tower Group Insurance companies exist. Customers were relocated to different providers, and claims were transferred as well.
